java.lang.Object
  org.glassfish.grizzly.filterchain.BaseFilter
      org.glassfish.grizzly.utils.SilentConnectionFilter

All Implemented Interfaces:

Filter

public final class SilentConnectionFilter
extends BaseFilter

Filter, which determines silent connections and closes them. The silent connection is a connection, which didn't send/receive any byte since it was accepted during specified period of time.

handleAccept

public NextAction handleAccept(FilterChainContext ctx)
                        throws java.io.IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when server channel has accepted the client connection. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleAccept in interface Filter

Overrides:

handleAccept in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

java.io.IOException

handleRead

public NextAction handleRead(FilterChainContext ctx)
                      throws java.io.IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when channel will become available for reading. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleRead in interface Filter

Overrides:

handleRead in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

java.io.IOException

handleWrite

public NextAction handleWrite(FilterChainContext ctx)
                       throws java.io.IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when some data should be written on channel. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleWrite in interface Filter

Overrides:

handleWrite in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

java.io.IOException

handleClose

public NextAction handleClose(FilterChainContext ctx)
                       throws java.io.IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when connection has been closed. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleClose in interface Filter

Overrides:

handleClose in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

java.io.IOException
